I'm a complete novice, so did a load of research before settling on this mount, and have been really pleased so far.
Polar alignment was far easier than I expected, I used the Star Adventurer mini Console Android app's Polar Clock Utility to find the correct position of Polaris. As others have mentioned the wedge is a little hit and miss as you tighten everything up, the latitude adjustment giving me the most movement, but I found that progressively tightening and slight adjusting that was easy to set in only a few minutes. The horizontal adjustment is more accurate, I tightened the two bolts to give allow on very slight movement with no slop, then used both horizontal knobs for alignment and just pinched these tight to secure everything. If / when I use a heavier load I might need to pinch the bolts as well, but for now this seems to have worked OK.
The polar scope illumination works well, but it's build quality could be better. The battery compartment lid serves as on / off, and the threads aren't that well cut, so it's a bit rough action screwing the lid on and hit and miss when it's turned off, so I'm removing the battery after use.
So far I've only used this once with EOS R 24-105mm lens mounted on Manfrotto XPRO ball head, and the Star Adventure mounted on Manfrotto MT055CXPRO3 tripod. This setup appears very stable, I've been able to get plenty of good (I'm my novice eyes!) pictures with 30 second exposures right up to 105mm with no star trails visible. The biggest challenge I found was to get accurate focus...
Once I've had a little more experience I'm planning to try longer lenses, and have done a practice set up with 150-600mm Sigma lens mounted on the L bracket / fine tuning assembly. With the supplied counterweight this balanced out with no problems at all, and appeared to be stable, but I've yet to take any photo's so can't yet comment just how good this will be with longer, heavier lenses
During my research I've read a load of Web articles and watched loads of YouTube videos, the ones I've found particularly helpful are those by Peter Zelinka. I've also found First Light Optics have an Android weather app "Clear Outside" to help forecast when the sky's will be clear, and the few nights I've tried this it seems pretty accurate
And finally, Sky-Watcher say that the Star Adventurer has lifetime firmware updates and also advanced firmware available. The latest firmware I found on their website is dated 25 March 2015 version 3.06. When I try to install this, it's not recognised in Windows 10, 7 or even XP (all 64bit versions) and there is no sign of the advanced firmware. That said, the version supplied by First Light Optics appears to be the latest, so no worries about upgrading anyway.
Overall, while there are are a few minor niggles, for the price this is an outstanding buy and I'm sure is far more capable than I'm ever likely to need and I can most definitely recommend it even for novices like me

Bought this for astro photography, polar alignmennt a nightmare even with the polar
Iluminater..the wedge which you slide the main unit on his not sturdy enough..by the time dslr 500mm lens and cameras on it and a star finder there's a bit Of sag on it..which knocks polar alignment out. So a faff to get on it again, unit track ok but.I noticed when you get near the pole on the celestial sphear the tracking was out! (Polar alignment?) Batteries don't last don't use cheapo ones! its compact but there's weight limit on it. I have it on a peer I made. Gona have to get a eq5 pro? To be fair I did get a good Orion nebulae picture first time out..so must done sumet right! Flo delvery fast has always good service used them many times.

Excellent product, sturdy so no worries with my DSLR fitted.

I received this mount last month and I've been very pleased with it so far. Results have been great even with sub-par polar alignment (My latitude prevents me from getting a clear view of Polaris). With a 300mm lens, I managed 1 minute subs with minimal trailing. Plop my Evostar 72ed on the mount and I reached 30 seconds with minimal trailing as well! I suspect that if I nailed down my polar alignment, my subs could be even longer! Would definitely recommend for beginners into imaging. The mount is also super compact; I could fit the disassembled mount and other accessories into my camera bag!

I' m happy! The package arrived super fast. The mount is amazing. First Light Optics, can you do something with the weather in Romania? I don' t think so. Thank you again for your professionalism. Clear skies!

This mount is a great addition to my astrophotography gear. I just used the mount for the first time up at Keilder forest. The mount polar scope helps with getting a basic initial alignment, and is as good as any polar scope that I've used before. Once a proper polar align was done using my AsiAIR, the tracking was excellent. Unguided I was easily able to take 1 min shots of M31, without any star trailing. Over the 120 exposures that I took, there was some drift, but not a huge amount. I'm sure that if I'd turned setup the auto guiding, that would have allowed even longer exposures.

The Star adventurer, was easy to balance with my WO SpaceCat 51, ZWO 290MM and MiniGuide Scope, red dot finder and Canon 70D with battery grip. Powering the mount from a USB Powerpack, saw no issues at all, and I'm very pleased with the outcome. The Star Adventurer wedge was easy to align and once locked down held it's position well. The telescope felt stable and I was confident that there was no issues with weight limits. I think this setup could easily hold something much larger, however I have no desire to try that out.

Top marks for this piece of kit, feel very sturdy and does everything I need right out of the box.

Bought this on 27 september, shipped the same day, should arrived on 8 october but arrived earlier (4 october), very well packed and intact.

Very heavy duty thing this, Full metal made wihtout some screw heads and caps. Oerration is very easy.

What an amazing piece of kit! Super easy to use, really quick to set up and start imaging with, light, portable, what's not to like!?
Managing to get 3minute unguided subs with a 300mm full frame lens on a crop sensor DSLR (Canon 700D), at this exposure and focal length just over half of my subs are usable, knock my exposure time down to 2 mins and i'm up to 85-90% usable subs. Batteries last forever too, done about 8-10 nights of imaging and the first batteries I put in are still going strong.
Just recieved my Evostar 72ED and field flattener as an upgrade to my 300mm lens from the 70's (SMC Takumar) which attatches to and balances on the Skywatcher without issue. Havn't had time to test this yet, but with many people already reporting good results with this combo i'm really looking forward to it, and will also be pairing it up with an ASIair and mini guide scope/camera in the coming weeks. All together the 72ED, DSLR, field flattener and mini finder scope only comes to 3.5KG, which is easily balanced by using the 1KG counterweight provided.

Lightweight, portable, the batteries last a long time. Excellent tracking up to 400 mm focal length. The weight capacity declared in my opinion is greater. Obviously it requires a good stable tripod and good polar align. Also great for making timelapse.
FirstLightOptics has the best price!!!
